Titles editing problems

Context :
Using v2 (1efc609) on Windows 7

Description :
When copying and pasting text in titles it doesn't paste the correct selection (and doesn't cut).

Scenario :
1/ Have a score with title = "My exemple" and subtitle = "problem" and an empty clipboard.
2/ Select in title "em" then cut and paste between "p" and "r" in subtitile => nothing is paste and selection is not deleted.
3/ Do the same but copying instead of cutting, it take in the clipboard one character before the selection plus everything until the end of line => subtitle = "pempleroblem"

Expected :
1/ Ability to cut and paste.
2/ Respect the selection.
